Title: Weapon pressure compensation system for increasing projectile velocity - diverts propellant gases into compensation chamber for maximum pressure on projectile
Inventor: RAHE MARTIN
IPC: F41A21/28
Filed: 1975-06-10
Abstract: The pressure storage system for firearm ensures the extension of the maximum pressure pulse for increasing the acceleration of a projectile. The cartridge chamber is filled with a high energy propellant or one which is more densely packed. The excessive gases generated on combustion initially are diverted into a pressure compensation chamber. Hence the overall pressure in the barrel bore and chamber is compensated so that the maximum value of the pressure does not exceed that on using conventional propellant charges. The pressure generates is continuously applied on the projectile in spite of the expanding vlume of the barrel bore as the projective travels. This arrangement ensues a longer maximum pessue exerting period and higher increased muzzle pressure for higher acceleration.

Title: DC motor with permanent magnet pole pieces - having V:shaped pole tips in circumferential direction
Inventor: VOLKRODT WOLFGANG DR ING
IPC: H01F13/00
Filed: 1975-12-29
Abstract: In order to obtain the advantages of non-abrupt entry and exit of the armature conductors and teeth into and out of the main pole flux in permanent magnet excited machines without skewing the armature slots the pole tip geometry is changed. The permanent magnet liners (2,3) forming the stator poles (N,S) have their axial sides (4,5) made in the form of V-notch and V-projection on opposite sides. This has the effect of progressive reduction of field strength at the pole tips and gives the desired result. By eliminating the need to skew the armature slots the armature core construction becomes simpler, and for mass production motors, the automatic coil and armature winding made easier.
